  • Publication number: 20240104487
    Abstract: One example method includes receiving information for a shipment, the shipment comprising one or more pieces, the information comprising information about a destination; receiving, from a remote dimensioning device, dimension information, the dimension information providing a length, a width, and a height for each of the one or more pieces; transporting, using one or more first transport vehicles, the shipment to a first shipper facility; allocating, using a first trained machine learning (“ML”) model and the dimension information, each piece of the shipment to one or more second transport vehicles and loading each piece of the shipment according to the allocating, wherein the first trained ML model is trained based on length, width, and height dimension information for one or more pieces; transporting, using the one or more second transport vehicles, the shipment to a second shipper facility; allocating, using a second trained machine learning (“ML”) model and using the dimension information, each piece of t

  • Patent number: 8715871
    Abstract: An electrochemical cell having two or more diffusion bonded layers, which demonstrates a high degree of ruggedness, reliability, efficiency and attitude insensitiveness, is provided. The novel cell structure simplifies construction and operation of these cells. Also provided is a method for passive water removal from these cells. The inventive cell, as well as stacks made using these cells, is suitable for use in applications such as commercial space power systems, long endurance aircraft, undersea power systems, remote backup power systems, and regenerative fuel cells.

  • Patent number: 7673178
    Abstract: Break and optional hold preserves a state of a computing environment on which a software program has failed. Being able to examine the status of the environment existing upon the occurrence of the failure, including the condition of various processes and values facilitates resolution of the cause of the failure. Upon occurrence of a failure during the execution of a first software program in a first computing environment, execution of the first software program breaks. A first state of the first computing environment existing upon the breaking in execution of the first software program is then held. A failure notification is generated to signal the failure to a monitoring system. The monitoring system accesses hold information to determine whether the first computing environment should hold its current state and whether one or more other computing environments interacting with the first computing environment should also hold their states.

  • Publication number: 20060003204
    Abstract: A fuel cell power plant fuel purge valve (26) is controlled in response to a parameter (40, 40a) of a fuel recycle blower which is indicative (20) of the recycle fuel impelled thereby, either alone or together with load current (33), pressure rise of the blower (50, 51), and temperature of the fuel recycle gas (44), to provide a pulse width modulation-control signal (28) controlling the purge valve.
